9.3 Power Consumption
This section details the power consumption of the device as measured during various modes of
operation. Power dissipation is determined by temperature, supply voltage, and external source/sink
requirements.
9.3.1 Operational / Unconfigured
9.3.2 Suspend / Standby
9.3.2.1 Single Supply
The following table details the device power consumption when configured with a single VBAT supply
For additional information on power connections, refer to Chapter 4, "Power Connections," on page 17.
Note: Typical values measured with VBAT = 4.2V. Maximum values measured with VBAT = 5.5V.
